Erythromycin

Erythromycin is an wide-spectrum antibiotic that is used in ophthalmic, topical, and systemic treatment of bacterial infections. It is particularly useful in patients with a history of allergies towards other antibiotics. The mechanism of action appears to be binding to the 50S ribosomal subunits in susceptible bacteria to suppress protein synthesis. Side effects include fever, nausea, skin rash, pain and swelling.
